Why not do something that would make an immediate impact:
Ban all diesel equipment engaged in construction of solar, wind etc farms and any other infrastructure. All construction must use battery/EV equipment as of 01/01/25
Ban all transportation of food & produce into or within the state via diesel powered semis, ships, locomotives etc. All such transportation shall be via EV/battery systems as of 01/01/25.
This will quickly solve the climate issue in CA as millions will flee the state or simply stop breathing.
